Disallows member access on a value with type any
.
Despite your best intentions, the any
type can sometimes leak into your codebase.
Member access on any
typed variables is not checked at all by TypeScript, so it creates a potential safety hole, and source of bugs in your codebase.
This rule disallows member access on any variable that is typed as any
.
Examples of code for this rule:
declare const anyVar: any;
declare const nestedAny: { prop: any };
anyVar.a;
anyVar.a.b;
anyVar['a'];
anyVar['a']['b'];
nestedAny.prop.a;
nestedAny.prop['a'];
const key = 'a';
nestedAny.prop[key];
// Using an any to access a member is unsafe
const arr = [1, 2, 3];
arr[anyVar];
nestedAny[anyVar];
declare const properlyTyped: { prop: { a: string } };
properlyTyped.prop.a;
properlyTyped.prop['a'];
const key = 'a';
properlyTyped.prop[key];
const arr = [1, 2, 3];
arr[1];
const idx = 1;
arr[idx];
arr[idx++];
// .eslintrc.json
{
"rules": {
"@typescript-eslint/no-unsafe-member-access": "error"
}
}
This rule is not configurable.
